▍What is CB Certification？
IECEE CB is the first genuine international system for mutual recognition of electrical equipment safety test reports. NCB (National Certification Body) reaches a multilateral agreement, which enables manufacturers to obtain national certification from other member countries under CB scheme on the basis of transferring one of the NCB certificates.
CB certificate is a formal CB scheme document issued by authorized NCB, which is to inform other NCB that the tested product samples conform to present standard requirement.
As a kind of standardized report, CB report lists relevant requirements from IEC standard item by item. CB report not only provides results of all required testing, measurement, verification, inspection and assessment with clearness and non-ambiguity, but also including photos, circuit diagram, pictures and product description. According to the rule of CB scheme, CB report will not take effect until it presents with CB certificate together.
▍Why we need CB Certification?
- Directly recognized or approved by member countries
With CB certificate and CB test report, your products can be exported to some countries directly.
- Convert to other countries certificates
The CB certificate can be directly converted to the certificate of its member countries, by providing the CB certificate, test report and difference test report (when applicable) without repeating the test, which can shorten the lead time of certification.
- Ensure the Safety of Product
The CB certification test considers the product’s reasonable use and foreseeable safety when misused. The certified product proves the satisfactory of the safety requirements.

On December 29, 2022, GB 31241-2022 “Lithium ion cells and batteries used in portable electronic equipment —— Safety technical specifications” was released, which will replace the version GB 31241-2014. The standard is scheduled for mandatory implementation on January 1, 2024.GB 31241 is the first Chinese mandatory standards for lithium-ion batteries. It has attracted a lot of attention from the industry since its release and has a wide range of applications. Lithium-ion batteries that apply to standard GB 31241 have been using CQC voluntary certification, but in 2022 it has been confirmed that they will be converted to CCC mandatory certification. So the release of new version of GB 31241-2022 foreshadows the upcoming release of CCC certification rules. Based on this, the following are two recommendations on the current battery certification for portable electronic products:For the time being, it is not recommended to update the CQC certificate to the latest version. As the implementation rules and requirements for CCC certification will be released soon, if you go to update the CQC certificate, you will still need to do a new update when the CCC certification rules are released. In addition, for the already existing certificate, before the issue of CCC certification rules, it is recommended to continue to update and maintain the validity of the certificate, and cancel them after obtaining the 3C certificate.
